ULTRASONIC DIAGNOSTIC APPARATUS

To simultaneously obtain good time responsiveness and a good space compound effect.SOLUTION: A first beam scanning plane FA and a second beam scanning plane FB are formed alternately. For formation of the first beam scanning plane FA, transmission/reception control is performed so that the beam deflection angle increases continuously toward the negative side from a first end to a second end in the electronic scanning direction. For formation of the second beam scanning plane FB, transmission/reception control is performed so that the beam deflection angle increases continuously toward the positive side from the second end to the first end in the electronic scanning direction.SELECTED DRAWING: Figure 3 【課題】良好な時間的応答性及び良好な空間コンパウンド効果を同時に得る。【解決手段】第１ビーム走査面ＦＡ及び第２ビーム走査面ＦＢが交互に形成される。第１ビーム走査面ＦＡの形成に際しては、電子走査方向における一方端から他方端にかけて、ビーム偏向角度が負側へ連続的に増大するように、送受信制御が実行される。第２ビーム走査面ＦＢの形成に際しては、電子走査方向における他方端から一方端にかけて、ビーム偏向角度が正側へ連続的に増大するように、送受信制御が実行される。【選択図】図３
